[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.
[0030] As shown in Figure 1 Figure 1 is a specific embodiment of the surgical suture forming device (hereinafter referred to as forming device) provided by the present application, which is used to form an elongated strip-shaped suture with a substantially rectangular cross section into a fishbone-shaped barbed suture a2 as shown in Figure 7 Figure 2.
[0031] As shown in Figures 1-3As shown, the molding device includes a male mold assembly 10 and a female mold assembly 20, wherein the male mold assembly 10 includes a male mold mounting plate 11 and at least two sets of male molds 12, and the female mold assembly 20 includes a female mold mounting plate 21 and at least two sets of female molds 22. The surfaces opposite to the male mold mounting plate 11 and the female mold mounting plate 21 are molding surfaces, and the molding surfaces between the male mold mounting plate 11 and the female mold mounting plate 21 are suitable for clamping the suture line a1 to be processed; the male mold mounting plate 11 is provided with a first direction ( Figure 1 The first plugging groove 111 extending in the X direction in the direction of the axis of rotation is provided on the female mold mounting plate 21, and at least two sets of male molds 12 are fixedly embedded in the first plugging groove 111 in sequence; the female mold mounting plate 21 is provided with a second plugging groove 211 extending in the first direction, and at least two sets of female molds 22 are embedded in the second plugging groove 211 in sequence. An elastic member 23 is further provided in the second plugging groove 211. In the initial state, a part of the female mold 22 is located outside the molding surface of the female mold mounting plate 21 under the action of the elastic member 23; Figure 6 As shown, the cross section of the female mold 22 is in the shape of a barbed line, that is, the cross section of the female mold 22 has at least two groups of barbed structures, and the cross section formed by the multiple groups of female molds 22 is consistent with the cross section of the barbed suture line a2 after molding; the molding surface of the male mold mounting plate 11 and / or the female mold mounting plate 21 is provided with a first limiting portion 112 / 212, and the first limiting portion 112 / 212 is suitable for being aligned with the suture line a1 to be processed along the second direction ( Figure 1 The surfaces relatively arranged in the Y direction (in the Y direction) cooperate to limit the position of the suture line a1 to be processed along the second direction, which is perpendicular to the first direction.
[0032] When the molding device is used, the female mold assembly 20 and the male mold assembly 10 are moved along the third direction ( Figure 1 The suture line a1 to be processed is moved between the female mold assembly 20 and the male mold assembly 10 through the clamping device, for example, Figure 1 As shown, when the female mold assembly 20 is located on the lower side, the suture a1 to be processed is placed on the upper surface of the female mold 22, and its left and right positions are limited by the first limiting portion 112 / 212. The male mold assembly 10 is controlled to move until the male mold 12 abuts against the suture a1 to be processed and closes the mold. The male mold assembly 10 is continued to be controlled to move a set distance. Under the action of the punching force, the female mold 22 moves into the second insertion groove 211. The suture a1 to be processed between the male mold 12 and the female mold 22 is cut and formed into a fishbone-shaped barbed suture a2 under the action of the punching force, realizing the one-time molding of the suture. At the same time, the first limiting portion defines the position of the suture in the second direction, ensuring the position accuracy and molding quality of the suture.
[0033] Specifically, the male mold 12 is embedded in the first insertion groove 111, and the female mold 22 is embedded in the second insertion groove 211. That is, the shape of the first insertion groove 111 matches that of the male mold 12, and the shape of the second insertion groove 211 matches that of the female mold 22. This allows the female mold 22 and the male mold 12 to mate with the second insertion groove 211 during the mold closing and stamping process, forming a barbed suture a2 that meets the requirements. Depending on the length of the suture, the female mold 22 and the male mold 12 can be provided in multiple groups, with multiple groups of female molds 22 and multiple groups of male molds 12 seamlessly connected.
[0034] Specifically, the elastic member 23 is a compression spring provided between the surface of the female mold 22 away from the male mold 12 and the bottom of the second insertion groove 211 , and the elastic force of the compression spring acts on the female mold 22 .
[0035] Optionally, in one embodiment, the cross-section of the male mold 12 is barbed linear, and the cross-sections of the surfaces facing the female mold 22 are consistent and overlap along the third direction, thereby improving the molding accuracy of the barbed suture. In an alternative embodiment, the cross-section of the male mold 12 is elongated, and the coverage area of the male mold 12 is larger than the coverage area of the female mold 22. During stamping, the second insertion groove 211 on the male mold 12 and the female mold mounting plate 21 limits the punching position of the suture a1 to be processed, which can also achieve the molding of the barbed suture.
[0036] Optionally, in one embodiment, the surface of the male mold 12 facing the female mold 22 is flush with the molding surface of the male mold mounting plate 11 or protrudes from the molding surface of the male mold mounting plate 11 .
[0037] In an optional embodiment, the first limiting portion 112 / 212 is at least two groups of limiting pins arranged along the first direction, each group of limiting pins including two limiting pins, the two limiting pins being respectively mounted on the forming surfaces of the male mold mounting plate 11 on both sides of the first insertion slot 111, and / or the two limiting pins being respectively mounted on the forming surfaces of the female mold mounting plate 21 on both sides of the second insertion slot 211. When installing the suture a1 to be processed, the suture a1 to be processed is placed between the two limiting pins of each group, that is, the limiting pins abut against two opposite side surfaces of the suture a1 to be processed along the second direction, thereby limiting the suture a1 to be processed along the second direction.
[0038] Specifically, the number of groups of the limit pins is determined according to the length of the female mold 22 and the male mold 12 in the first direction. In an optional embodiment, at least two groups of the limit pins are arranged in the area where each group of the female mold 22 / the male mold 12 is located along the first direction.
[0039] In an alternative embodiment, the male mold mounting plate 11 and the female mold mounting plate 21 are respectively provided with a plurality of groups of pin holes on the molding surfaces thereof, each group of pin holes is arranged in pairs along the second direction, and each group of pin holes on the male mold mounting plate 11 and the female mold mounting plate 21 is coaxially arranged along the third direction. The two sides of the pin shaft are respectively arranged in the coaxially arranged pin holes of the male mold mounting plate 11 and the female mold mounting plate 21.
[0040] In order to ensure the positional consistency of the plurality of groups of the female mold 22 and the male mold 12, as shown in Figure 4 , the first insertion slot 111 of the male mold mounting plate 11 is provided with a second limiting part 113, the second insertion slot 211 of the female mold mounting plate 21 is provided with a second limiting part 213, and the second limiting parts 113 / 213 are adapted to cooperate with the female mold 22 / male mold 12 to limit the position of the female mold 22 / male mold 12 along the second direction. The second limiting parts 113 / 213 can fine-tune the position of the female mold 22 and the male mold 12 along the second direction, thereby ensuring the positional consistency of the plurality of groups of the female mold 22 and the male mold 12.
[0041] Specifically, in an alternative embodiment, the second limiting part 113 provided on the male mold mounting plate 11 is an insert block detachably connected in the first insertion slot 111, one side surface of the insert block abuts against the male mold 12, and the position of the male mold 12 can be adjusted by adjusting the position of the insert block relative to the first insertion slot 111. Similarly, the second limiting part 213 provided on the female mold mounting plate 21 is an insert block detachably connected in the second insertion slot 211, one side surface of the insert block abuts against the female mold 22, and the position of the female mold 22 can be adjusted by adjusting the position of the insert block relative to the second insertion slot 211.
[0042] Specifically, in an alternative embodiment, as shown in Figure 1 , Figure 3 , one insert block is arranged for each group of the female mold 22, and one insert block is arranged for each group of the male mold 12. In other embodiments, the number of insert blocks can also be selected according to the length of the female mold 22 and the male mold 12, for example, two or more insert blocks are arranged for each group of the female mold 22 / male mold 12.
[0043] Specifically, in an alternative embodiment, the male mold mounting plate 11 is detachably connected by a first half male mold plate 11a and a second half male mold plate 11b, the first half male mold plate 11a and the second half male mold plate 11b are respectively configured as plate bodies with notches on one side, the notches on the opposite sides of the first half male mold plate 11a and the second half male mold plate 11b are arranged opposite to each other and connected and fixed by a fastening assembly, and the notches on the opposite sides of the first half male mold plate 11a and the second half male mold plate 11b form the first insertion slot 111.
[0044] Similarly, the female mold mounting plate 21 is detachably connected by a first half female mold plate 21a and a second half female mold plate 22b, the first half female mold plate 21a and the second half female mold plate 22b are respectively configured as a plate body with an opening on one side, the first half female mold plate 21a and the second half female mold plate 22b are opposite to each other through the opening and are connected and fixed by a fastening assembly, and the opposite opening parts between the first half female mold plate 21a and the second half female mold plate 22b form the second plug-in slot 211. Since the shapes of the first plug-in slot 111 on the male mold mounting plate 11 and the second plug-in slot 211 on the female mold mounting plate 21 match the shape of the barbed suture a2, the male mold mounting plate 11 and the female mold mounting plate 21 are designed as two-part plate bodies that are detachably spliced, which facilitates processing and manufacturing and reduces production costs.
[0045] Obviously, the above embodiments are only examples for clearly illustrating, but not limit the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments cannot be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
